What is the Arab Spring? Radicals overthrowing radicals in an attempt to replace them with even radicalers?

The people across the Middle East haven't been rising up against the ruling class because the ruling class isn't "radical" enough. They've been rising up against them because their lives are shit and the government isn't doing shit about it, and in many cases making it worse. With, of course, some Islamist elements trying to pounce on the opportunity, which one can't ignore.

That's the whole dynamic of the Spring, though. Look up social contract theory, the guiding principle of the Declaration of Independence. The purity at the heart and soul of that was driving the Spring. And in many places, still is.

With moves like this, the US is just further entrenching itself in the "we don't care as long as we get to make money" -- if we're willing to make money off antidemocratic dictators killing their people in the streets, then we're empty suits.
